Looks to me like you ran out of memory.
You need tons of ram for Gentoo these days.
Grab a old harddrive and make a big chunk of swap.
That recently got me through a update._________________Donate to Gentoo

I have plenty of ram off this server which is odd. i submitted a question to the devs and they blamed it on gcc. It looks like once i try to compile the code memory does take a dump. must just be some bad coding in there somewhere causing it to be a resource hog. i've got several instances off aws so will just spin up another or look for alternatives in getting this to compile. thanks
